Abstract: A method for distributed allocation of data paths in an optical network (100) including optical switches (30, 32, 130) connected by optical links (44, 140), includes receiving a request for a data path for connecting a source node (10) and a destination node (20). In in response to the request, one or more queries are sent, the queries corresponding to one or more candidate optical circuits that connect the source node and the destination node, the queries requesting one or more processors (230) to configure the optical switches along the candidate optical circuits to reserve optical channels on the optical links of the candidate optical circuits for the requested data path. An optical circuit is identified from among the candidate optical circuits, in which all the optical channels for the requested data path have been reserved successfully. The requested data path is established over the identified optical circuit.

Abstract: A routing controller (30) includes an interface (68) and multiple processors (60). The interface is configured to receive a permutation (76) defining requested interconnections between N input ports and N output ports of a Benes network (24). The Benes network includes multiple 2-by-2 switches (42), and is reducible in a plurality of nested subnetworks associated with respective nesting levels, down to irreducible subnetworks including a single 2-by-2 switch. The multiple processors are configured to collectively determine a setting of the 2-by-2 switches that implements the received permutation, including determining sub-settings for two or more subnetworks of a given nesting level in parallel, and to configure the multiple 2-by-2 switches of the Benes network in accordance with the determined setting.

Abstract: Apparatuses, systems, and associated methods of manufacturing are described that provide a dynamic data interconnect and networking cable configuration. The dynamic data interconnect includes a substrate, transmitters supported on the substrate configured to generate signals, and receivers supported on the substrate configured to receive signals. The dynamic data interconnect further includes a number of connection pads that receive data cables attached thereto and a number of transmission lanes that operably couple the transmitters and receivers to the connection pads. The dynamic data interconnect further includes transmission circuitry in communication with each of the transmitters and receivers such that, in an operational configuration, the transmission circuitry determines a transmission state of the dynamic data interconnect and selectively disables operation of at least a portion of the transmitters or at least a portion of the receivers.

Abstract: A network element (36) includes circuitry and at least one port (72). The at least one port is coupled to an optical fabric (32) including one or more optical switches (40) that provide optical paths between the at least one port and multiple destination nodes, at predefined time slots. The circuitry is configured to hold a schedule plan (84) that specifies which of the destination nodes are accessible via the optical fabric at which of the time slots, to queue packets that are destined to the destination nodes, and to transmit the queued packets via the at least one port in accordance with the schedule plan.

Abstract: Apparatuses, systems, and associated methods of manufacturing are described that provide an optical interposer and associated communication system. An example optical interposer includes a substrate having a first end that receives a first optical fiber welded thereto and a second end that receives a plurality of photonic integrated circuits (PICs) attached thereto. The interposer further includes an optical waveguide network defined by the substrate that provides optical communication between the first welded optical fiber and the plurality of PICs. The optical waveguide network also includes optical redistribution elements supported by the substrate. In an operational configuration, the optical interposer receives a first input optical signal from the first welded optical fiber, and the plurality of optical redistribution elements successively split the first input optical signal such that a plurality of output optical signals is directed to the plurality of PICs.
